Researchers conducted a randomized evaluation to measure the impact of peer referrals by current patients on the screening and identification of tuberculosis cases in India. Peer referrals and outreach by current patients to identified peers were more effective than health-worker led contact-tracing, while combining these interventions with financial rewards was a cost-effective strategy to improve tuberculosis screening and detection.

In partnership with Family Bank of Kenya, researchers evaluated the impact of providing free ATM card to couples on savings account use. Providing ATM cards significantly increased the use of savings accounts owned by men and joint accounts on average, but had no effect on accounts owned by women or men that had less bargaining power than their spouses.

Employers in the low-skill and entry-level job market often lack information on job seekers’ abilities, which can reduce interview invitations and job offers for job seekers, especially for disadvantaged groups such as women. Researchers partnered with the South African Department of Labour to evaluate the impact of reference letters on employer response rates and on employment outcomes for unemployed young people.

For-profit (and often online) universities account for nearly half of all postsecondary growth over the last decade, yet relatively little is known about how employers value and compare these education types. To test this, researchers randomly submitted resumes with different characteristics and post-secondary credentials to measure the impact of education type on prospective employer interest. For jobs that did not require a degree, there was no advantage to having a postsecondary credential from a for-profit institution. However, resumes with for-profit postsecondary credentials were over 20 percent less likely to receive callbacks for jobs that did require a degree.

Researchers evaluated how well different measures of teacher effectiveness predicted student performance in six school districts in the United States. Measures of teacher effectiveness based on student achievement in the previous year, classroom observations, and student surveys accurately identified which teachers produced higher average student test scores.

Researchers investigated whether access to information about local labor laws could improve firms’ understanding of the law. They found that free access to an existing subscription service that provided this information improved firms’ understanding of labor regulations and resulted in large employment gains.

Researchers evaluated the impact of photographic monitoring technology on aggregation fraud and perceptions of government legitimacy during the 2010 parliamentary elections in Afghanistan. The announcement of a new monitoring technology reduced both theft of election materials and vote counts for politically connected candidates and increased perceptions of government legitimacy.

Researchers studied how a school grant program affected learning outcomes and household spending. After the first year of the grant program, students in treatment schools performed significantly better than those in comparison schools, but by the end of the second year, there was no detectable impact on student learning.

Voters in Benin had a preference for clientelist political platforms, but certain subsets of voters such as women, consumers of mass media, and members of social organizations were less receptive to clientelism.

Understanding workplace incentives and the motivations of workers is important for increasing workplace productivity and organizational efficiency. Many have suggested that employees are altruistic, willing to work harder when they believe that the amount of effort they exert in their job directly translates into value for their organization. Researchers conducted a randomized evaluation to measure the impact of different employee and employer payoffs on the productivity of workers hired to stuff envelopes for either one of several charities or for a grocery store. The results indicate that employees were more productive when compensated, in part, for the number of envelopes they completed. Furthermore, workers were more likely to exert effort when their work was of value to their employer but did not increase their effort when the value to their employer was greater. Workers did not change their effort in response to receiving a surprise increase or decrease in pay.

A key challenge to achieving universal health coverage is that non-poor informal workers are difficult to enroll and retain in government health insurance programs. Researchers conducted a randomized evaluation to test the impact of various programs, including subsidies, registration assistance and information campaigns on the enrollment and retention of non-poor informal workers in Indonesia’s national health insurance program. Registration assistance and subsidies both increased household enrollment, but overall enrollment rates remained low.

Researchers randomly provided free fertilizer to women rice farmers in southern Mali to measure how farmers chose to use the fertilizer, what changes they made to their agricultural practices, and the profitability of these changes. The fertilizer grants led to increased fertilizer use, use of complementary inputs such as herbicides and hired labor, and yields, yet did not lead to substantial increase in profit.
